About Me
Software engineer by day, founder of two small companies on the side — always looking for ways to build something useful.
I'm Gunawan Santoso, a software engineer based in Jakarta, Indonesia. I've spent the past several years working at companies like Shopee, Gojek, and Waresix — building frontend systems, shipping products, and learning what it takes to create software that people rely on every day.
I also founded two small companies — Micro App Digital, where I create simple apps for everyday use, and Incrementum, a digital solutions company that helps businesses build and grow their online presence.
AI is a natural extension of the workflow — from faster prototyping to better code, it frees up energy for the decisions that actually matter. The craft stays human, the speed just gets multiplied.

Small steps, better growth — thoughtfully designed apps to help make your day a little easier.
Micro App Digital is where I independently design, develop, and publish mobile apps. Each app is something I built from scratch on my own — from the idea and design to the code and release. The goal is always the same: make something simple, useful, and well-crafted that solves a real everyday problem.

Incrementum
A digital solutions company that helps businesses design, build, and grow through technology.
Incrementum (PT Incrementum Digital Solution) is a digital solutions company I started to help businesses with their technology needs — from web development and mobile apps to internal dashboards and e-commerce platforms. We also provide penetration testing and network security assessments to help clients identify vulnerabilities and strengthen their infrastructure before threats become problems.
What Drives Me
Build with purpose
Every product should solve a real problem. I focus on utility over complexity — creating tools that genuinely improve how people work and live.
Put users first
Great software starts with understanding the people who use it. Clean interfaces, thoughtful interactions, and accessibility aren't afterthoughts — they're the foundation.
Grow incrementally
Whether it's a personal app or a client project, I believe in shipping early, iterating often, and letting real feedback guide the direction.
